Construction of the equestrian venue for the Hangzhou 2022 Asian Games has begun with a main stadium, racetracks and stables all part of the work.

Training, logistic and commercial facilities, as well as an Athletes' Village, are also planned for the facility in the Chinese city.

Equestrian events in Hangzhou are due to last 11 days, with riders expected from 22 countries and territories with around 230 horses.

It is expected to be the largest horse-riding contest ever at the Asian Games.

The site in Tonglu will be classified as an equine disease-free zone, to ensure the horses' safety.

Last month, work started on the zone including in the forestry, agriculture, finance and transportation departments.

The Government plans to complete the construction of the venue by the second half of 2021, while the World Organisation for Animal Health will provide assessments at the site.

All pig, cattle and goat farms will be relocated from the core area, which covers five square kilometres.

Around 536 horses have been implanted with chips that record health information, vaccine records and whereabouts.

This information will be available as part of Hangzhou's "City Brain" system.

Horses are susceptible to diseases such as glanders, Japanese encephalitis and equine influenza.

Vice-mayor of Hangzhou Wang Hong said: "We will digitise the construction of the zone in Hangzhou, expanding the capacity of the City Brain system and improving Government services.

"That is an opportunity for us to enhance our management level."

All horses will arrive in Hangzhou by air and will then be transported to Tonglu through a "biodiversity route" starting at Xiaoshan International Airport.

Hangzhou will have the second equine disease free zone in China after a similar one was created in 2018 in Guangzhou.
